LB-15 Memory

[WGJ]

Does anyone know what the base memory for stored part programs is on a mid 80's LB-15 with the OSP-5000L-G? Thanks.

I believe it was 60 Meters tape storage and 30 M program capacity. If you look in the back of your control, there should be a data management card that shows how your machine was spec'd out and what memory it has. If you press the FREE button with a ;C after it, it will show you your memory status and how much contiguous is open.

Bubble memory.....hehehe. I assume you mean there is a page that turns an "f" button into free since I do not have just a 'free' button on the control panel... Could you elaborate? Also, I do not understand memory in terms of meters, so could you give me an equivalent in terms of Kb? Thanks.

I believe he means(correct me if I am wrong OkumaWiz), 60 meters of "tape" capacity. Technology so old I've never even seen it used. Not that I've been around since raccoon hats, am just aware of tape readers.

And 30 megs of program memory.

Well, yes, coon hats are very comfortable - unless you're a coon! Okuma decided from the good ol' tape days to express their memory in terms of meters as if they were paper tape. So much for moving forward... Anyway, your control should have the FREE key - it's just buried in the edit mode. Go to your edit mode and hit the extend key and your FREE key will show up. Push it and then type the ;C and press write. You should see your memory displayed.

If I remember right, there are 12 characters per inch, so doing the math, 30 meters should give you about 14K of runnable program space and about 30K of storage for programs. No it's not in MB of storage like anything newer. Bubble was awesome for it's day, but expensive. You would have to spend about $15K just to get about 1.5 MB of storage from Okuma - yikes!

Fortunately, CNC code is extremely efficient, so the small memory works for most shops - if you use Okuma's canned cycles it even better. Remember every character counts - spaces, line numbers, leading and trailing zero's, unneeded decimal points ,so get rid of them all if you are in a crunch - none are needed by the control.

May your bubble memory never burst!

I had never calculated meters directly to kbytes. It seems, that 1" contains 1 byte. or 0,1" ?
very easy to check with 3½" Floppy disk. OSP shows it's full capacity in meters, and You can calculate easy then, knowing that You use either 1,5MB Floppy or 720kB.
When OSP displays capacity (command FREE), it's not only in meters, but in "characters" also. Is that right? That way is easy to calculate again: 1 character = 1 byte (8 bits)

hi there
the 2. is with igf it has more free space then without.

without igf you have near 10K free, and some free on BB0.

OSP 5000L with IGF got 16k of memory space
